Bishop was a Synthetic crew member assisting the Colonial Marine Corps aboard the USS Sephora sent to the Zeta II Reticuli system to investigate the 'mUSS Sulaco in search of Ellen Ripley, Corporal Dwayne Hicks, and the rest of the missing marines who were dispatched to LV-426 19 weeks earlier.
Bishop appears in the opening credits examining Captain Winter and again in the cargo bay. After he is on comms communicating with Winter in his missions and appears again when O'Neal and Winter releases Hicks who had been held by Weyland's PMCs, then continues with them arriving aboard the last W-Y FTL finding Michael Bishop aboard.
- Bishop was rumored to be named Rook (but this was proven to be false).
- Bishop's first line is ad-libbed: "Don't ask me to do the knife trick. I can see it in your eyes." This references actor Lance Henriksen's constant requests to do said trick by many of the fans he met over the years.
